The KEEN® Utility Gibson Waterproof Work Boots (Carbon Toe) are a streamlined, lower-profile version of the work boots you grew up with. They've got a supple leather upper and carbon toe married to an energy-returning KEEN.ReGEN midsole for a perfect blend of strength and sleekness. The all-day comfort and grippy rubber outsole make it versatile enough for your whole life - work to weekend and everything in between. These ankle-high boots are built on KEEN's Original Fit, giving extra room for toes to spread out and extra support. They are made of a foam insole and mesh lining. The KEEN.DRY waterproof, breathable membrane liner keeps your feet dry and comfortable. Their full-grain barnyard-resistant waterproof leather helps resist the damaging effects of oleic acid, urea, sodium chloride, and ammonium hydroxide, while the cement construction provides flexible, lightweight performance. These dependable work boots are great for medium-duty work in roofing, construction, utilities, landscaping, maintenance, and energy. The faux welt of these boots delivers classic work boot style, while their heat-resistant rubber outsole is rated up to 572°F/300°C. These work boots are designed with left and right asymmetrical, non-metallic carbon toes, made of composite material, offering an unobtrusive fit and are 15% lighter than steel. These boots meet or exceed ASTM F3445 and F2413 M I/75 and C/75 standards.
